Abstract
The utility model discloses a kind of devices of suitable imbedded and perched shellfish parent shellfish oviposition, the device includes the frame body of cuboid, four side of bottom of the frame body is made of tubular structure, the tubular structure is equipped with aeration aperture, and also it is connected with gas ducting, the top of the frame body is the support body of a unenclosed construction, and the centre of the support body is an enclosed rectangle structure body, and the inside of the rectangle structure body is equipped with multiple parallel crossbeams；The device further includes oviposition frame, which is equipped with purse seine.Present apparatus structure is simple, ingenious in design, induces that the oviposition of close shellfish, cost is relatively low, easy to operate using inflation, and few to the injury of close shellfish, Oviposition speed is fast, ovum quality is good, and hatching rate is high, takes a firm foundation for the artificial breeding of imbedded and perched shellfish.
Description
Technical field
The utility model relates to a kind of devices of shellfish oviposition, and in particular to a kind of suitable imbedded and perched shellfish parent shellfish oviposition
Device.
Background technique
At present China imbedded and perched shellfish (such as clam, Ruditapes philippinarum, mud blood clam, razor shell, clam, Coelomactra antiquata, razor clam of hanging,
Ba Fei clam etc.) it is many kinds of, yield is maximum, cultivates the supply of seed mainly by seedling rearing in earth ponds and seeding-growth, and gentle by weather
Time is affected, and it is many that seed supplies uncertain factor, and room heat source generally production level is lower, produces in close shellfish room
Ovum is difficult, and emergence rate is low and high production cost is its main cause, and wherein the indoor accelerating of imbedded and perched shellfish parent shellfish is cultivated and oviposition is
Technical bottleneck, the oviposition technical system that can manually regulate and control at any time without imbedded and perched shellfish parent shellfish so far.Imbedded and perched shellfish parent at present
Shellfish oviposition mainly using dry in the shade, heat up stimulus method, ammonia seawater impregnate and injection oviposition method, wherein dry in the shade, heat up stimulus method, lay eggs
High-quality, egg laying amount is smaller, and the injection of ammonia seawater and infusion method, induced spawning effect is good, but the archiblast difference and hatching rate of output are low,
It is not easy to cultivate, therefore, it is difficult to obtain a large amount of good fertilized eggs required for artificial breeding, can not also carry out large-scale artificial nursery
And breeding.
Therefore, there is an urgent need to it is a kind of it is easy to operate, save labor, the side of imbedded and perched shellfish parent shellfish oviposition convenient for management
Method, while ensuring that the ovum quality of output is good and fast, to meet artificial breeding production needs, and wherein it is suitable for imbedded and perched shellfish
The device of close shellfish oviposition is unusual the key link.
Summary of the invention
The purpose of the utility model is to provide a kind of easy devices of suitable imbedded and perched shellfish parent shellfish oviposition, existing to make up
There is the deficiency of technology.
In order to achieve the above objectives, the utility model take the specific technical proposal is:
A kind of device of suitable imbedded and perched shellfish parent shellfish oviposition, which includes the frame body of cuboid, the frame
Four side of bottom of frame ontology is made of tubular structure, and the tubular structure is equipped with aeration aperture, and is also connected with gas ducting, described
The top of frame body is the support body of a unenclosed construction, and the centre of the support body is an enclosed rectangle structure body,
The inside of the rectangle structure body is equipped with multiple parallel crossbeams；The device further includes oviposition frame, and the oviposition frame is four in addition to top
Week is equipped with purse seine.
Further, the top of the frame body is equipped with tether, and the other end of the tether is equipped with floating ball, is used for device energy
It is enough to be steadily in seawater, and the water depth that adjustable apparatus is in.
Further, the top perimeter of the oviposition frame is equipped with side slot, for being held on crossbeam.
Further, tubular structure also is provided among the bottom of the frame body.
The advantages of the utility model and technical effect:
The utility model structure is simple, ingenious in design.The gas ducting and aeration aperture that the present apparatus is equipped with using bottom are inflated
Close shellfish is induced to lay eggs, cost is relatively low and easy to operate, it is important that it is few to the injury of close shellfish, can reach close shellfish oviposition speed
Degree is fast, ovum quality is good, and the beneficial effects such as hatching rate height are taken a firm foundation for the artificial breeding of imbedded and perched shellfish.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Wherein, 1- frame body, 2- tubular structure, 3- aeration aperture, 4- gas ducting, 5- support body, 6- crossbeam, 7- system
Rope, 8- floating ball, 9- oviposition frame, 10- purse seine, the side 11- slot.
Specific embodiment
The utility model is explained further and is illustrated below by way of specific embodiment and in conjunction with attached drawing.
Embodiment 1:
A kind of device of suitable imbedded and perched shellfish parent shellfish oviposition, which includes the frame for the cuboid that PV pipe is assembled into
